## Background
RELATED APPLICATIONS
This application is a 371 application of International Application No. PCT/KR2008/003064, filed May 30, 2008, which in turn claims priority from Korean Patent Application No. 10-2007-0053974, filed Jun. 1, 2007, both of which are incorporated herein by reference in their entirety.
TECHNICAL FIELD
The present invention relates an upper body support apparatus for supporting the upper body of a user who sit on a toilet.
BACKGROUND ART
Generally, when most users sit on toilets and have bowel movements, they bend their upper bodies forwards and place the arms on the legs.
However, such a posture makes the users develop bad habits, in other words, assume bad posture unconsciously in daily life. Furthermore, such a posture has a bad influence on bowel evacuation.
Furthermore, in the case where the users strain to evacuate their bowels in the above posture, there is a problem in that blood pressure is increased, thus negatively affecting the body.
Recently, the number of constipated persons has markedly increased attributable to excessive stress and attempts to lose weight. In the case of such constipated persons, due to anxiety when having bowel movements, it becomes still more difficult to have smooth bowel movements.
In particular, if there were a separate apparatus which enabled people to conduct other routine work for the several minutes for which the persons have bowel movements, it would be a great help to people with busy lives.
To achieve this purpose and overcome the above-mentioned problems, an upper body support board for toilets was proposed in Korean Utility Model Registration No. 390267 (application date: Apr. 14, 2005, registration date: Jul. 11, 2007), which was filed by the applicant of the present invention. The conventional upper body support board includes a support board to support the arms of a user thereon, a support rod, which is coupled to the support board to support the support board, and a mounting rod, into which the support rod is inserted so as to be rotatable relative to the mounting rod within a predetermined angular range, and which is installed in a lavatory to position the support board and the support rod at a predetermined position in the lavatory.
In the case of the upper body support board disclosed by the applicant of the present invention, samples have already been developed, and the commercialization thereof has been conducted. Furthermore, there was a very positive response. Particularly, the upper body support board evoked a good response from the old and the weak. However, in the case of the conventional upper body support board, the support board is relatively heavy, so that it is difficult for the old or the weak to lift or push the support board. Furthermore, there is a disadvantage in that, in the winter, when a user places his/her arms on the upper body support board, the user may feel a chill due to the cooled support board. Therefore, a solution to these problems is required.

As shown in FIGS. 1 through 4, the upper body support apparatus 10 according to the present invention is provided at a predetermined position adjacent to a toilet 1 to support the upper body of a user. The upper body support apparatus 10 includes a support board 11, on which the arms of the user are placed, a horizontal shaft 13, which provides a path along which the support board 11 slides relative to the horizontal shaft 13, a hinge unit 15, which supports a first end of the horizontal shaft 13 such that the horizontal shaft 13 is rotatable upwards or downwards within an angular range of 90° around the first end thereof, and a vertical frame 17, which supports the hinge unit 15 and receives therein a drive unit 19, which rotates the hinge unit 15 to the left or the right or moves the hinge unit 15 upwards or downwards in a one-touch button control manner.
In the present invention, a receptacle 11a, a cover of which is closed so as to be openable using a hinge, is provided in a medial portion of the upper surface of the support board 11. Transparent windows are disposed in the support board 11 on opposite sides of the receptacle 11a. Far infrared lamps 11b are provided inside the respective transparent windows. Bent edges 11c for guiding the sliding movement of the support board 11 are integrally provided under respective opposite side edges of the lower surface of the support board 11 and extend predetermined lengths in the longitudinal direction. A cushion member 11d is adhered to the upper surface of the support board 11.
Here, the far infrared lamps 11b serve to emit light and heat outside the apparatus through the transparent windows, thus taking off the chill in the winter.
Furthermore, an ultraviolet lamp may substitute for the far infrared lamp 11b. In this case, the transparent windows are preferably made of semitransparent material to partially intercept ultraviolet rays such that the skin of the user is prevented from being injured by excessive exposure to ultraviolet rays.
The bent edges 11c correspond to a guide plate 13a of the horizontal shaft 13, which will be explained later herein, and thus serve to guide the sliding movement of the support board 11 along with the guide plate 13a. 
In addition, a substance, which is made of rubber, silicone or sponge and is covered with a leather cover, may be used as the cushion member 11d. 
Meanwhile, the horizontal shaft 13 is a pipe, which defines therein a space, in which power supply wires for the far infrared lamps 11b are placed. The guide plate 13a, corresponding to the bent edges 11c of the support board 11 to guide the sliding movement of the support board 11, is fastened to the upper surface of the horizontal shaft 13.
Here, the guide plate 13a is provided on a second end of the upper surface of the horizontal shaft 13 having the pipe structure, and occupies about 1⁄2 of the length of the horizontal shaft 13. Due to this construction, the support board 11, which slides relative to the vertical shaft 13, can be stably extended from the vertical shaft 13 outwards to an appropriate length.
Furthermore, a support block 13b, which is a support such as a bracket, is provided under the lower surface of the horizontal shaft 13. The support block 13b is brought into contact with the outer surface of the upper end of the vertical frame 17, and thus serves to support the weight of the user, which is applied to the support board 11.
The hinge unit 15 includes a bracket, to which the first end of the horizontal shaft 13 is coupled by a hinge 15a, and which is partially cut such that the horizontal shaft 13 is rotated within an angular range of 90°, in other words, between the horizontal direction and the vertical direction. The hinge unit 15 is provided on the lower surface thereof with a support shaft 15b and a support bearing 15c. 
Here, the hinge 15a may be coupled to an output shaft of a motor, which is provided outside the hinge unit 15, such that the rotation of the support board 11 can be automatically conducted by manipulation of the user.
Furthermore, the support shaft 15b passes through an upper end of an upper frame of the vertical frame 17, which will be explained later herein, and is coupled to an output shaft of a left-right rotating motor, thus serving to transmit left-right rotating force.
The support bearing 15c is interposed between the hinge unit 15 and the upper surface of the upper frame of the vertical frame 17 such that the hinge unit 15, which is seated on the upper surface of the upper frame of the vertical frame 17, can be smoothly rotated.
The vertical frame 17 includes the upper frame 17a, which supports the hinge unit 15 on the upper end thereof and is provided on the outer surface thereof with a control pad 19a having key buttons for controlling the drive unit 19, and a lower frame 17b, which is fastened to the floor in the lavatory and supports the upper frame 17a, the lower end of which is inserted into the lower frame 17b. Here, the lower frame 17b supports the upper frame 17a such that the upper frame 17a is movable only in the vertical direction, without rotating relative to the lower frame 17b. 
To achieve this purpose, a guide groove G is formed in the circumferential outer surface of the upper frame 17a and extends from the lower end of the upper frame 17a to the medial portion thereof. A guide protrusion P defining a path along which the guide groove G is moved upwards or downwards is provided in the lower frame 17b. 
Then, when a motor for moving the upper frame 17a upwards or downwards relative to the lower frame 17b is operated, the upper frame 17a can be moved only upwards or downwards, without undesirably rotating.
Furthermore, a stop ring T is provided on the lower end of the upper frame 17a. A stopper S is provided on the upper end of the lower frame 17b to prevent the stop ring T from being undesirably removed from the lower frame 17b. The stopper S may be an annular cap, which is fitted over the upper end of the lower frame 17b. 
Due to this construction, even if the upper frame 17a is excessively moved upwards, it is prevented from being removed from the lower frame 17b. Furthermore, the lower frame 17b can support the upper frame 17a such that the upper frame 17a slides upwards or downwards along the circumferential inner surface of the lower frame 17b without undesirably moving.
Meanwhile, the drive unit 19 includes a control means 19b, which conducts the operation, corresponding to a command selected by manipulating the key buttons of the control pad 19a, using power transmitted from the outside, and the left-right rotating motor 19c, which is reversibly rotated to rotate the hinge unit 15 to the left or the right in response to an operating signal transmitted from the control means 19b. The drive unit 19 further includes the lift motor 19d, which is reversibly rotated to move the lower frame 17b upwards or downwards in response to an operating signal transmitted from the control means 19b. 
Preferably, the left-right rotating motor 19c is installed in the upper end of the upper frame 17a, and the lift motor 19d is installed in the lower end of the upper frame 17a. 
Furthermore, a lead screw having an external thread is used as the output shaft of the lift motor 19d, and is constructed such that it is inserted through a support plate, which is provided in the lower end of the lower frame 17b, so as to be rotatable in a screwrotating manner. Here, the support plate is fastened to the circumferential inner surface of the lower frame 17b, and the central portion thereof is fitted over the output shaft of the lift motor 19d so as to be rotatable in a screw-coupling manner.
In the present invention having the above-mentioned construction, as shown in FIG. 5, when the user sits on the toilet and rotates the support board 11, which is disposed at a position adjacent to the toilet, downwards to the front of the upper body of the user, the first end of the horizontal shaft 13, which is hinged to the hinge unit 15, is rotated around the hinge unit 15. Then, the support board 11, which is slidably coupled to the horizontal shaft 13, is oriented in the horizontal direction in the front of the upper body of the user.
Therefore, as shown in FIGS. 6 and 7, when the support board 11 is pulled in the direction away from the horizontal shaft 13, the support board 11 is extracted from the horizontal shaft 13, that is, the length thereof is extended, under the guidance of the bent edges 11c of the support board 11, which slide relative to the guide plate 13a of the horizontal shaft 13.
Here, the length extension can be appropriately adjusted to suit the body type of the user.
After the support board 11 is moved to the front of the upper body of the user, if the user does not want to support his/her upper body on the support board 11, or, if the user does not want to use the support board 11 for a while in order to conduct other routine work, the support board 11 can be rotated in the horizontal direction towards the wall in the lavatory by manipulating left-right rotating control buttons, which are provided on the control pad 19a of the drive unit 19.
In detail, as shown in FIGS. 8 and 9, when the left rotating control button of the control pad 19a of the drive unit 19 are pushed, the left-right rotating motor 19c is rotated in the normal direction, so that the support board 11 is rotated in the horizontal direction towards the wall in the lavatory. When it is desired to use the support board 11 again, the right rotating control button is pushed. Then, the left-right rotating motor 19c is reversely rotated, so that the support board 11 is rotated towards the user, thus enabling the user to use the support board 11.
Furthermore, as shown in FIGS. 10 through 12, to match the sitting height of the user, for example, in the case where the sitting height of the user is relatively high, when a corresponding button among vertical control buttons, which are provided on the control pad 19a of the drive unit 19, is pushed, the lift motor 19d is rotated in the normal direction. Then, the upper frame 17a has a tendency to rotate relative to the lower frame 17b, to which the output shaft of the lift motor 19d is rotatably screwed, but, because the guide protrusion P of the lower frame 17b is placed in the guide groove G in the upper frame 17a, the upper frame 17a is moved upwards without rotating relative to the lower frame 17b. 
In the case where the sitting height of the user is relatively low, when a corresponding button of the vertical control buttons of the control pad 19a of the drive unit 19 is pushed, the lift motor 19d is reversely rotated. Then, the upper frame 17a is moved downwards without rotating relative to the lower frame 17b by the same principle as that in the description of the upward movement of the upper frame 17a. 
In the present invention, even if no drive signal is transmitted from the control means 19b to the left-right rotating motor 19c or the lift motor 19d, particularly, even if no power is applied thereto, the apparatus can be operated by a manual method. Moreover, because a reserve charging battery for supplying emergency power is provided in the control means 19b, even in emergency conditions, such as during a power failure, the apparatus can be operated for some time.
Furthermore, as described above, referring to FIG. 13, the receptacle 11a having the openable cover may be provided in the medial portion of the upper surface of the support board 11. The far infrared lamps 11b may be provided inside the respective transparent windows, which are disposed in the support board 11 on opposite sides of the receptacle 11a. 
In this case, the far infrared lamps 11b emit heat, as well as far infrared rays, which are beneficial to the human body, through the transparent windows, thus taking off the chill in the winter. Here, an ultraviolet lamp may substitute for the far infrared lamp 11b. In this case, the transparent windows preferably have a function of partially intercepting ultraviolet rays, thus preventing the skin of the user from being injured by excessive exposure to ultraviolet rays.
Furthermore, the present invention may further include a vibration unit 20, which is provided under the lower surface of the support board 11 at a position adjacent to the user. In this case, the present invention can have a function of massaging the abdomen of the user. That is, the user brings his/her abdomen into contact with the vibration unit 20 and pushes a control button of the control pad 19a corresponding to the vibration unit 20. Then, the vibration unit 20 massages the abdomen of the user. In particular, in the case of a constipated user, the vibration unit 20 stimulates the large intestine of the user, thus enabling easy evacuation of the bowels.
Here, the vibration unit 20 may be coupled to the support board 11 in a fitting manner or a screw coupling manner. As well, the vibration unit 20 may be constructed such that the inclination angle thereof relative to the forward direction can be adjusted.
Furthermore, the vibration unit 20 may comprise a device, which vibrates using the rotation of a motor, which is connected to a power wire that extends into the horizontal shaft 13 having the pipe structure. Here, the vibration of the vibration unit 20 using the rotation of the motor may be realized by rotation of an eccentric body.
In consideration of the movement of the power wire connected to the vibration unit 20 due to the sliding movement of the support board 11 relative to the horizontal shaft 13, it is preferable that a slot, through which the power wire is extracted from the horizontal shaft 13, be formed in the horizontal shaft 13.
Furthermore, the cover of the receptacle 11a is preferably constructed such that a book can be supported on the cover. In addition, various objects of the user can be contained in the receptacle 11a so that they are prevented from falling from the support board 11.
Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, the present invention is not limited to the construction and operation of the illustrated embodiment. Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
Therefore, such modifications, additions and substitutions must also be regarded as falling within the bounds of the present invention.
INDUSTRIAL APPLICABILITY
As described above, an upper body support apparatus of the present invention enables a user to place his/her arms on a support board while having a bowel movement, thus maintaining correct posture such that the upper body of the user is prevented from leaning too far forwards, thereby preventing an increase in blood pressure attributable to the bowel movement.
Furthermore, under normal conditions, the support board can be placed adjacent to a wall in an upright state or in a horizontal state. Hence, in a lavatory having limited space, free movement of the user is ensured, and the upper body support apparatus is prevented from impeding the opening or closing of a door of the lavatory.
As well, in the present invention, the support board can be automatically rotated downwards or upwards, and is thus opened or closed by manipulating control buttons in the one-touch button control manner. Therefore, even the old and the weak can easily use the upper body support apparatus.
Furthermore, a heat generating means or a sterilization means is provided in the support board, thus enabling maintenance of the body temperature of the user in the winter, and improving personal sanitation in a lavatory in which it is hard to continuously maintain a sanitary state.
In addition, in the case where the upper body support apparatus of the present invention is used for the old and the weak, in particular, the old, having poor metabolism, the upper body support apparatus of the present invention can promote the bowel movement, thus guiding smooth bowel evacuation.
Moreover, the present invention enables the user to place his/her arms thereon and, as well, enables a book or cosmetics to be placed thereon, thus making it possible to conduct other routine work as well as the bowel evacuation.
